Climbing Rose plant named &#39;KORcaseipp&#39;

ABSTRACT

‘KORcaseipp’ is a new and distinct variety of  Rosa hybrida  which is characterized by the combination of a climbing growth habit, an abundance of large and very double-type flowers which are pastel apricot in color and also attractive foliage with very good disease resistance. The new variety propagates successfully by grafting and by stem cuttings and has shown to be uniform and stable in the resulting generations from asexual propagation.

LATIN NAME OF GENUS AND SPECIES

The Latin name of the genus and species of the novel variety disclosedherein is Rosa hybrida.

VARIETY DENOMINATION

The inventive variety of Rosa hybrida disclosed herein has been giventhe variety denomination ‘KORcaseipp’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct Rosa hybrida,climbing rose cultivar, of the market class PLT/109.

Parentage: The Rosa hybrida variety ‘KORcaseipp’ is the result of acontrolled cross-pollination breeding program carried out by theinventor in Offenseth-Sparrieshoop, Germany. The objective of the saidbreeding program was to create a new and distinct rose plant with uniquequalities, such as:

1. Uniform growth and flowering;

2. Abundant attractive, recurrent flowers;

3. Attractive and abundant foliage; and

4. Resistance to diseases encountered in landscapes and gardens.

This combination of qualities is not present in prior rose cultivarsknown to the inventor. These objectives have been substantially achievedand in that distinguish ‘KORcaseipp’ from all other varieties known tothe inventor.

‘KORcaseipp’ is a seedling selection which resulted from the controlledpollination of two proprietary Rosa hybrida cultivars, developed andowned by the same inventor, during the summer of 1998. Saidcross-pollination was made between the seed parent, Rosa hybrida‘KORkinteral’ (unpatented), and the pollen parent, Rosa hybrida‘KORpastato’ (unpatented).

As part of a rose development program, Tim-Hermann Kordes germinatedseeds from the aforementioned hybridization during the winter of 1998and conducted evaluations and observations on the resulting seedlings ina controlled environment in Offenseth-Sparrieshoop, Germany. Theresulting seedlings exhibited distinctive physical and biologicalcharacteristics. The new rose plant was selected as a single plant inMay of 1999 from the seedling beds due to its superior characteristicsand asexually propagated for further evaluation. This new anddistinctive rose variety was given the name ‘KORcaseipp’.

Asexual Reproduction: The first asexual propagation of ‘KORcaseipp’ wasdone by budding in July of 1999 at the inventor's nursery inOffenseth-Sparrieshoop, Germany and has since been successfullyasexually propagated by stem cuttings and grafting in Jackson County,Oreg. These initial and other subsequent propagations conducted incontrolled environments demonstrate that ‘KORcaseipp’ reproduces true totype in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following characteristics have been repeatedly observed andrepresent the distinguishing characteristics of the new Rosa hybridacultivar ‘KORcaseipp’. These traits, in combination, distinguish‘KORcaseipp’ as a new and distinct cultivar.

1. Rosa hybrida ‘KORcaseipp’ exhibits a climbing growth habit; and

2. Rosa hybrida ‘KORcaseipp’ exhibits an abundance of flowers; and

3. Rosa hybrida ‘KORcaseipp’ exhibits a very-double flower type; and

4. Rosa hybrida ‘KORcaseipp’ exhibits a large flower size; and

5. Rosa hybrida ‘KORcaseipp’ exhibits a pastel apricot flower color, atanthesis; and

6. Rosa hybrida ‘KORcaseipp’ exhibits semi-glossy foliage; and

7. Rosa hybrida ‘KORcaseipp’ exhibits very good disease resistance.
